Death claimed him, but ‘She’ brought him back. He still had use.

Kairan awoke in the aftermath of his accursed quest twisted. A shade of his former self, a monster. A boon granted by the Fell God he’d woken.
The friends who’d travelled with him gone, all eight dead for a reason he could scarcely comprehend. Heroes. That is what they had been called. Now it felt more like sacrifices.
Harbouring an unnatural hunger for violence, he sets out in search of the truth: why were they chosen for this quest and why was he cursed for completing it? Those responsible will find in him their ruination.
Meanwhile, ‘Her’ voice whispers to him from beyond the veil, dangling knowledge before him in exchange for his labour.
